Hello @Michelle4882
A hard no!! You are a new host and this type of scam request is not unknown I'm afraid. They want to take you off platform obviously and I would simply reply that this is not allowed by Airbnb and your photos are a true reflection of the listing.
Did this request come through as an enquiry or as a trip request by the way? Airbnb require different things from us depending on how this came through.
As for asking a deposit, this is only permitted if you go through a Channel Manager AND that it is clearly stated on your listing as a requirement.
